Each lot of LVR can vary & you likely have a fast barrel with your Pacnor. Both factors may be calling for backing off your loads considerably if we are to believe the data.
If your primer pockets have grown to a point that you are experiencing loose primer seating, Id tend to believe your data to a larger degree.
I do expect you likely did make an error with your charge weight the 29.5 grain load with the velocity you experienced. I expect you were close to 31 grains on that group of rounds. could be wrong though that is the direction the data is pointing. Will take time though this is part of the process of coming to trust your equipment & the nut operating the equipment.
I understand you have a bit of a long drive to utilize a range, Though IMHO you are working with a mistaken notion that Hornady data should duplicate if you use the provided recipe in your rifle. If that is the case, you have proven to yourself , your rifle is not hhe same as there test rifle. Once you wrap your head around this you may come to understand that from one powder to the next you may need to back off a grain & a half or more from upper end loads.
Until you prove otherwise I'll encourage you to stay well off upper end loads while you are getting your feet grounded with all of the process. Patience & close observation will serve you well. Glad you have the Magneto speed for feed back. If your Magneto speed is correct & again I suspect it is the data you are seeing in very valuable.
Going forward being more diligent double checking yourself till you are more familiar & confident in your process would be prudent.
